Application March 8, 1940, Serial No. 322,910

2 Claims. (01. 215-38) bility of any loss of the liquid contents whichmay result from spillage or evaporation.

Another object of our invention is to provide a novel cap for bottlescontaining perfumes and similar volatile liquids which will eflicientlyseal the liquid contents of the bottle and at the same time permit theparticular odor of the perfume to be determined without the necessity ofremoving the cap from the bottle.

Other objects of the invention will be set forth in the followingdescription and drawing, which illustrate preferred embodiments thereof,it being understood that the above statement of the objects of theinvention is intended generally to explain the same without limiting itin any manner.

Fig. 1 is a sectional view along line l-l of Fig. 2, the bottom part ofthe bottle being shown broken away.

Fig. 2 is a top plan view of one embodiment of the invention.

Fig. 3 is a sectional view of another embodiment of the invention. 7

Fig. 4 is a top plan view thereof.

Fig. 5 is a sectional view of still another embodiment of the invention,and

Fig. 6 is a top plan view thereof.

Fig. 7 is a sectional view of another embodiment.

Fig. 8 is a sectional view along line 88 of Fig. '7.

Referring to the drawing, the reference letter B designates any ordinarytype of bottle having the neck-portion N. A thread, designated by thereference letter T is formed on the outer face of said neck N.

Referring specifically to the embodiment of the invention shown in Figs.1 and 2, l designates a metal cap or closure having the thread 2 formedin the cylindrical face thereof, said thread being adapted to engagethread T of the neck N of the bottle. A plurality of perforations oropenings 3 are formed in the top wall 6 of cap I. Liners 4 and 5 arelocated below the inner surface of the top wall 8 of cap I. Liner l,positioned below and adjacent the perforations 3, may be made of anysuitable absorbent material such as absorbent paper, absorbent cotton,blotting paper, etc. Located below and adjacent to liner 4 is disc 5,said disc being formed of an impermeable material such as metal foil orcork. Members 4 and 5 may be secured to each other or a single linerhaving its upper part porous and its lower part non-permeable, may beemployed.

When cap I is in closed position on bottle 3, top wall 6 of said cappresses disc 5 against the top wall of the neck N of the bottle, thuseffectively sealing the contents of said bottle. Absorbent liner 1 maybe saturated with material 'similar to the contents of the bottlethereby enabling a person to ascertain the scent or odor of saidcontents without removing the cap from the bottle. The openings in thetop wall of the cap permit the vapors of the material impregnated'inliner 4 to pass therethrough.

The embodiment of the invention illustrated in Figs. 3 and 4 differsfrom the embodiment just described principally in that the cap I is madeof a plastic or other similar material and has a thread formed on itsinner cylindrical face and secondly, instead of a plurality ofperforations, only one perforation or opening 3a is formed in the topwall of said cap. Liners 4 and 5 are similarly located as in the firstembodiment, illustrated in Figs. 1 and 2. Absorbent liner 4 isimpregnated with a sample of the liquid in the bottle so that apurchaser can determine the scent or odor of the contents of the.bottle, without removing the cap.

In addition, a cylindrical sleeve 8 may be provided said sleeve fittingsnugly over the cap I, said sleeve being adapted to receive any type ofdesign, ornamentation or printed matter. Sleeve 8 may be made from anysuitable material and may be secured to cap I by any suitable means.

A third embodiment of the invention is illustrated in Figs. 5 and 6.This embodiment comprises a stamped metal cap I, having a thread Itformed in the cylindrical wall thereof, said thread being adapted toengage the thread T formed on the neck of the bottle. Positioned betweenthe top wall of the neck of the bottle and the inner surface of the topwall. 9 of cap I is the nonpermeable disc 5, said disc being firmly andsnugly held against the top wall of the neck oi. the bottle by said capI, thus eilectively sealing the liquid contents of the bottle. Anabsorbent liner 4 is positioned on the outer surface of top wall 9 ofcap I, and disc I I, having perforations or openvT on the neck ofthebottle.

ings l2 formed therein, is positioned atop said liner 4. v

Members 6 and II are snugly held against the outer surface of top wall 9of cap I by means of a sleeve l3, said sleeve fitting snugly around thecap and having an inwardly formed bead ll located at its upper edge. Theinner edge of said bead presses downwardly against the top of disc IIand holds said disc II and absorbent liner 4 securely in place.Absorbent liner 4 is impregnated with a sample of the liquid contents ofthe bottle, so that the particular o'dor or scentof the materialcontained within the bottle may be ascertained without the necessity ofremoving the cap from the bottle. Printed matter or any design orornamentation may be carried by the outer face of sleeve l3 and saidsleeve may be made from anydesired material.

The embodiment illustrated in Figs. 7 and 8 shows substantially the samearrangement as the last described embodiment as it would be appliedwhere the cap is made of a plastic or similar material. Cap l5 has athread i6 formed in its inner cylindrical wall adapted to engage thethread Extending above the top I! of cap I5 is the cylindricalperipheral wall l8 forming the circular recess I9. Located in saidrecess are the absorbent liner 4 and perforated disc If; In thisembodiment there is also provided a sleeve l3 having a. bead l4 formedalong its top edge, said bead being adapted to hold the members II and lsnugly within recess l9.

We have shown preferred embodiments of our invention, but it is obviousthat numerous changes and omissions may be made without departing fromits spirit.

The invention may be applied to any type of bottle, vial or container.

We claim:

1. In combination, a bottle having a neck-portion, a closure cap fittingover said neck-portion, an impermeable liner member adapted to seal theliquid contents of the bottle positioned on the top wall of theneck-portion and abutting the inner surface of the top wall of the cap,a porous liner positioned on the outer surface of the top wall of thecap, a perforated disc superimposed on said porous liner, a sleevemember adapted to snugly fit over the cylindrical wall of the cap, saidsleeve member having an inwardly formed bead located at its upper edge,the inner edge of said bead adapted to exert downward pressure againstthe top of the perforated disc and hold the said disc and porous linersecurely in place when the cap is applied to the neck of the bottle.

2. In combination, a container having a neckportion, a closure caphaving a top wall and a cylindrical wall fitting over said neck-portion,an impermeable liner member adapted to seal the liquid contents of thecontainer positioned on the top wall of the neck-portion and abuttingthe inner surface of the top wall of the cap, the cylindrical wall ofsaid cap extending above the top wall thereof thus forming a recess, aporous liner positioned on the outer surface of the top wall of said capwithin said recess, a perforated disc superimposed on said porous linerwithin said recess, a sleeve member adapted to snugly fit over thecylindrical wall of the cap, said sleeve member having an inwardlyformed bead located at its upper edge, the inner edge of said beadadapted to exert downward pressure against the top of the perforateddisc and to hold said disc and porous liner securely in place within therecess where the cap is applied to the neck of the container.
